DOOR FOR GRAIN-CARS.

Specification ot Letters Patent.

Application led December 2, 1911. Serial No. 663,638.

To alt whom! t may concern:

Be it known that I, THOMAS C. CHAM- BERS, citizen of the United States,residing at Mauguio, in the county of Greer and State ot Oklahoma, haveinvented certain new and useful Improvements in Doors vfor Grain-Cars,of which the following is a specification.

This invention relates to doors for grain cars. l

Uneobject is to 4-provide a folding door for grain cars arranged so thatit may be Afolded into the car 'when the car is empty and so th at itmay be folded out-ward against the outside of the c'ar vwhen it isdesired to remove grain or other commodity from the car, the door beingformed preferably of sections hinged together so that the opening of thedoor outwardly will not be interfered with by the elevator which carriesthe grain from the car.

Another object is to provide a door for grain cars embodying sectionshingedly connected together so that the door may be opened .and fittedinto a small space between the outside of the car and the elevator withone of the sections provided with a gate adapted to be opened to relieveundue pressure from. within the car on the door.

A still further object is to provide a grain car with doors, which maybe folded inL wardly or outwardly of the car and which when closing thedoor opening of the car may be connected together to sustain thepressure on the inside oithe doors incident to the weight or quantity ofthe grain within the car.

With the above andother objects, in View, the present invention consistsin the combination and arrangement of parts hereinafter more fullydescribed, particularly pointed out in the appended claims and.

y illustrated in the-accompanying drawings,

it being understood that changes may be made in the form, proportion,size and minor details without departing from the spirit or sacrificingany of the advantages of the invention.

In the drawings z-Figure 1 is a side ele. vation of the invention withthe door closed. Fig. 2 is a horizontal sectional view of one side oithe car showing the door open. Fig. 3 is a horizontal sectionalview'through a portion of the car showing the doors closed and connectedtogether. Fig. 4 is a sectional view taken verticallv through the reliefgate.

Referring now more particularly to the accompanying drawings,thereference character 10 indicates the sides of the car, each providedwith a doorl frame 11, to provide door openings. Secured to oppositesides of the door frame 11 are door jambs 12 andA 13, the door jamb 12being secured within the edges of the frame of the door opening with thejamb 13 secured to the inner side of the corresponding door fra-me andextending inwardly of the door opening and provided with locking keepers14 for a purpose presently explained.

Each door is composed of sections 15, 16 and 17, said sections beingconnected together on their outer faces by means of suitable hinges 18with the section 15 hingedly connected yby means of hinges 19 to theinner side edge of the door frame and with the section 150i the doordisposed normally 'against the jamb 12, when the door is closed.Thelsection 17 of each door is provided with a plurality of openings 20to aline with the keepers 14 so that the keepers 14 may pass through theopenings 20 and receive the locking bolts 21, which are secured by meansof chains or other suitable elements 22 to the section 17 of the doorand through the instrumentality of which locking elements 22, the doorsmay be held against outward movement incident to pressure 'against thecar.

To relieve undue or unnecessary pressure of' grain against the doors, Iprovide one of the sect-ions with an opening 23, and this opening ispreferably formed in the section 17, of each door. On opposite sides ofthe opening 23, I preferably dispose suitable guide-ways 24 in which mayslide a gate 25 which has secured to it a chain or other suitableelement 26 secured to the section 17 so asto prevent displaceinentbf thegate 25 when the latter is Withdrawn fromv the guide-ways 24. By raisingthis gate 25, grain may fall from. the car to the desired amount and forany desired purpose but preferably to relieve undue pressure of grainagainst the doors. l

It will be clear from the accompanying drawings, how the doors areclosed and fastened and when the doors are closed and it is desired toopen the same it is simply necessary to remove the locking bolts 21 fromengagement with the keepers 14.

The sections 16 and 17 may be maintained in alinement and both swungtogether on as the sections 16 and 17 are swung on the hinges 18 whichconnect the sections 15 and 16, they may be folded, first folding thesections 17 toward thesection 16. In any event and in View of ytheelevator (not shown) usually employed for conveying the grain from thecars, being rather close to the cars, it is preferred to fold thesections 1G and 17 with vrelation to each other and to shift them on thehinges 18 which connect the sections 16 and 17 in such a '.vay that thedoors as they are swung open may be caused to occupy very little space,for sometimes the space between the elevators and the cars .is verysmall and this has been one serious objection to doors adapted to swingopen toward the elevators. lVhen the cars are emptied, the doors maybeswung inwardly to occupy very small spa'cc by folding the sections 17on the sections 16 and then swinging the sections 15 of each door on thehinges 19 so that the folded sections 1 6 and 17 may lie against theinside of the car against the side thereof.

Sometimes the pressure within the cars, due to the quantity of graintherein, induces considerable pressure, and if desired, I may connectopposite doors by means of suitable stays 27, preferably in the form oflinks and connected to eyes 2S secured to the inner faces of the doors,as will be apparent by reference to Fig. 3. bviously more than -one ofthese door-connection stays 27 may be used if desired.

It will thus be seenthat 1 provide a. comparatively simple, inexpensive,durable and eiiicient grain car door and one'that may be rreadily foldedinwardly or'outwardly of the car to occupy very little space eitherinside or outside of the car.

What is claimed is 1. The combination of a car provided with a dooropening, a door composed of sections hingedly connected together, meansfor hingedly connecting the sectional door at one side only, of the dooropening, means the. remaining sections with the remaining sections beinget substantially the same width and hingedly connected so that theoutermost ot said remaining sections irma-sr be swung outwardly on theladjacent section and the said latter sections swung on the narrowersection and, whereby the door may be swung from one side only of thedoor frame opening either inwardly of the car or outwardly along theoutside of the car and occupy small space on the outside of the ear.

2. The combination of a car provided with a door opening, door jambssecured to opposite sides of the door opening, a door 'which is composedof three sections, two of which are substantially the same width andhingedly connected together, the remaining section being comparativelynarrow and hingedly connected at one side of the door opening adjacentone of said jambs and also .hingedly connected to the innermost of saidother two sections, the outermost one of saidI two sections havingopenings along its outer edge, elements secured adjacent the jambopposite the one to which said narrow door .sectitn is hinged forprojection through said openings, means carried by the outermostot'asaid ltwo sections for engagement with said elements to lock thedoor, the hinged connection between said two sections per mitting theoutermost section to be` swung upon the innermost of said two sectionswith the hinged connection between theinnermost of said two sections andwith the narrow section permitting the door to be swung back outwardlyof the car along the outer side of the latter with the hinged connectionbetween said narrow section and the door frame opening permit-tingswinging movement of the door inwardly of the car.

. In'testimony whereof I affix my signature in presence of twowitnesses.
